plus water from the mop or any saturated fabric.

In the drawings:*Figure 1 is a vertical cross section onthe line 1, 1 ofFig. 3, with the operating lever raised to nearly a vertical position;Fig. 2 is a fragmem tary: view showing a modification of the movablepresser in cross section; Fig. 3 is a rear elevation of the wringer; andFig. 4 is a side-elevation of the same.

Similarnumerals refer to similar parts in all the views.

'lhe wringer, broadly speaking, coniprisesa frame supporting astationary presser, a cooperating movable presser, means for attachingthewringer to a pail and means for operat ing and adjusting the movablepresser.

The side frames 1 and 2 of the wringer are of the form shown in Figs. 1and 4, and are preferably made of metal. A stationary-presserboard 3,supported between lugs or flanges 3 on the frames, separates the sides.and the hitter are held in place by transverse bolts 4.

1. Tongues (5, bearing against the outside of the pail, and the ends 7touching the inside, hold the wringer securely in place.

In the upper part of each side-plate is a horizontal slot 8. Theoperating-shaft 9 extends through both of said sl0ts, having a slidingfit therein. Holes 10, in line with the slots 8, form bearings foranother shaft 11, parallel to the operating shaft.

The mnvable presser. as illustrated in Fig. 1, issupported between twochanneled bars 12, and comprises two perforated plates 13 and '14..Brackets lfi on said bars support the bottom piece 16, which is usuallyof wood, as are also the presser'plates'13 and-14. A' transverserod orbolt 17, connecting the lower ends of the side plates 1 and'2, forms apivot for the bars 12. The operating means for moving the pressenplatismtached to ears or lugs 18 on the rear of said bars. The

upper supplemental part 13 of the resser-plate is piv- Openings or slots5 in the sides 1 and 2 areadapted to fit overthe edge of a pail, asshown in Fig.

, squeezed. 7

against the rear of the supplemental plate 13 and is held in place bystuds 22 screwed into the bars 12 through slots 21 in said spring. Theupper edge of the spring pressed nleinher 13 projects inwardly beyondthe inner face of the member 14 so that when the movable presser ismovedtoward the fixed presser 3 its upper spring pressed part l3willbegin to squeeze the mop at its top just in advance of the action by.the member 14. This prevents the water from being thrown upward andalso makes provision for inequalities in the mop being In Fig. 2 isshown a modified form of the movable presser. In this case the side barsare made in two sections 24 and 26, which are pivoted together at 23.

A presser plate 25 is supported between the two upper sections. Thisplate is normally held back bya leaf spring 27, which is screwed at 28to the bottom plate 29, and is bent upward against said plate. Anotherfiat spring 27 secured to the lower section 26 bears against the otherside of said presser-plate, in a direc tion contrary to the spring 27.The presser-plate 25 is thus yieldingly held in an upright position,- inalinement with the lowersection 26. Ears or lugs 18 project from therear of the bars 24, and a spring'40 is slipped over each. The pivot, atthe end of each operating link 32 slides in a slot 40 in said ears, andthe spring 40 acts as a cushion between said link and the pressenplate25, to prevent breakage of .the latter.-

7 The operating mechanism, or means for moving the presser-plate. isactuated by the movement of the handlever 30. which is fixed in a casing39 at one end of the shaft 9. Near each end of said shaft is fixed apair of oppositely-disposed cranks, one of each pair being hetween theside frames 1 and 2. and the other of each pair being just outside thesaid frames. (Figs. 1 and 4.)

Links 32 pivoted at 44 connect the inner pairof cranks 31 with the earsor lugs 18, and similar links 36 and 37 pivoted at 45 connect theoutside cranks 34 and 35 with pins 38, which project outwardly from theends of the shaft 11. When the lever 30 is depressed toward thestationary plate 3, the shaft 9 turns in the slot 8, and the cranks 31,34 and 35, and their connecting pivots, react as a powerful compoundtoggle between the pins 38 and the presser-platel4, and the latter'is,therefore, moved into proximity to the plate 3, with sufficient force tosqueeze nearly dry a mop or similarly saturated lever 41 outward. it maybe turned to the desired posi- I tion, and then held in place by astationary'pin 43, which is adapted to enter any one of a number ofholes 42 in said lever.

Movement of the lever 30 beyond a certain point is prevented by a stopor lug 35 on the casing 39,- which comes in contact with the underside'of one link 36.

when said lever is depressed to nearly a horizontal position. I

What I claim is 1. A mop \vringer comprising a frame having parallelside pieces provided with transverse slots, a stationary presser memberfixedly secured between said side pieces, a movable presser membersupported between said side pieces, an operating rock shaft turning inand. movable along said slots and provided with oppositely disposedcranks, links pivotally connecting. the-cranks with the movable pressermember and with a relatively fixed hearing respectively, and means forrocking said shaft.

2. A mop wringer, comprising a frame having parallel side piecesprovided with transverse slots, a stationary presser member fixedlysecured between said side pieces,'a movable presser member pivotallysupported at its; l ower portion betweensaid side pieces, an operatingrock shaft turning in and movable along said slots and provided withoppositely disposed cranks, links pivotally connecting the cranks withthe movable presser member and with a relatively fixed bearingrespectively, means for adjusting said a relatively fixed bearing tochange the throw of the operating rock shaft and its links.

3. A mop wringer, comprising a frame having parallel side pieces,provided with transverse slots, a fixed presser member fixedly securedbetween said side pieces,,-a movable presser member pivotally supportedat its lower end between said side pieces, a rotary adjusting shaftjournaled in said side pieces at a distance from said presser member, anoperating; rock shaft rocking in and movable along said h'ansverse slotsin said side pieces, parallel with said adjusting rock shaft, andbetween it and said movable presser member, and havingloppositelydisposed cranks, a link connecting said movable presser member-and oneof said cranks, asecond link connected at one end eccentrically to saidrotary adjusting shaft and at its other end end between said sidepieces;

part carried by said movable presser member, and pivot to the oppositecrank, means for imparting rotary adjust- ,ment tosaid last mentionedshaft, and means for rocking the operating shaft.

4. In a mop wringer, a frame comprising parallel side pieces havingtransverse slots, a stationary presser member held in fixed positionbetween said paralleL side pieces, a movable presser memberpivotallysupported at its lower, end between said side pieces, a rotaryadjusting shaft journaled in said side pieces at a distance from saidpresser members and provided with an eccentric pin, an operat ing rockshaft movable in the transverse slot in said side pieces, parallel withsaid rock shaft, and between it and said movable presser member, andhaving opposite disposed cranks, a link connecting said movablepressermember and one of said cranks, a second link connected at oneend" tothe eccentric pin on said'rotary shaft and at itsv other end tothe opposite crank, means for rocking theoperating shaft, a lever forrotating the adjusting shaft,"and means for locking said lever.
